Convert values to values inside a range in c++ , optimized using boost or std
boost, c++, optimization, std
Solution
I don't think using elaborate constructs would buy you much here. Maybe making your code a bit cleaner ?
std::for_each(std::begin(vElem), std::end(vElem), [](float &val) {
val = clamp(val, minVal, maxVal);
});
this is what a typicall clamp function returns
Problem
I want to validate all the elemnent of an array. If an element is under a value, swap by a min value and if it is above a value, swap by a max value. But I don´t know how I can do it optimized. For do it I go above all elements, element by element but it is not optimized, and it spend a lot of cpu time in very large arrays. This is an example of my code: ``` #include <iostream> #include <math.h> const int MAX = 10; int main () { float minVal = 2.0; float maxVal = 11.0; float vElem[] = {-111111.0/0.0, 10.0, 90.0, 8.0, -7.0, -0.6, 5.0, 4.0, 33.0, 222222222.0/0}; for(int i=0; i<MAX; i++){ if(isinf(vElem[i])==-1 || vElem[i]<minVal) vElem[i] = minVal; if(isinf(vElem[i])==1 || vElem[i]>maxVal || isnan(vElem[i])) vElem[i] = maxVal; std::cout << vElem[i]<< std::endl; } } ```
